Val(n) is described here.
Expression a ? b : c is usual for C++/C# and means if a then return b else return c
Thanks for the screenshot.
In the screenshot we see that /input/601 is bound to the channel #601 (because of the number in the Channel column). If there is no “15” in the UI, open the SCADA-Server shell, go to the Current Data node, open current.dat and view the current value of 601 channel. Is it 0 or “15”?Hi,
When you send a command from Webstation, it goes to Server and can be modified by formula. Server passes the command to Communicator. When you send a command from Communicator, there is no calculations.I am wondering what can be shaved from the OS work load (and the SCADA installation) if all I need is the ScadaComm & ScadaServer, with no need for ScadaWeb / Interface / ScadaTable etc.
In case of Windows installation, tick Server and Communicator checkboxes.
Interface folder is required by SCADA-Server, because it provides views to the web app.Hi,
So, on Linux if I do not need the web server, which steps can I safely skip during the installation process?
See install_with_apache.txt
Skip steps 3, 7, 8, 9, 10, 11, 15Hi,
Please post here version of the Webstation app and version of Extra Scheme Components Plugin.
Look the log file in SCADA\ScadaWeb\log for additional error description.Hi,
Calculated channels are ignored by the export module because they are recalculated many times in a second.
Unable to enqueue current data
You should check ModDBExport.log file to find the error cause.
Hi,
HTTP is generic. You should specify your own REST API and then develop the appropriate driver for Communicator. We can do this for you.
Why do you prefer HTTP in your case?An established connection was aborted by the software in your host machine.
May be an MQTT bus initiates disconnect. I’m not sure, because the author of the driver is bersim. You can try asking him or debug the driver by yourself. Also you can involve me in debugging on commercial base.
Hi,
Of course.Hello,
You can set a span in an address link, for example
